[PATCH] drm/amdgpu: added function to wait for PSP BL availability

[Chen, Guchun]

-             /* there might be handshake issue with hardware which needs delay */
-             mdelay(20);

To be safety, I don't think we should remove this delay. And this actually do nothing with the code refine in this patch.
